Top 10 Water Treatment Circuit Board Recycling Equipment Suppliers in China | 2025 Rankings and Reviews

Founded in 2008 and based in Zhengzhou, GreenTech has earned its top spot by redefining what circuit board recycling equipment can do. Walk into any major recycling plant in Europe or Southeast Asia, and you’ll likely spot their WCBD-2000A dry separation system humming away. What makes them special? They’ve mastered the balance between dry and wet processes, ensuring that even the trickiest circuit boards—those with layers of plastic, metal, and glass—get separated with 98% purity.

Clients love their flexibility, too. Whether you’re a small facility processing 500kg/hour or a mega-plant handling 2000kg/hour, they tailor systems that fit your space and budget. "We were drowning in e-waste until GreenTech installed their WCBD-2000A," says Maria Gonzalez, operations manager at a Spanish recycling firm. "Now we’re not just compliant—we’re turning a profit by selling recycled copper and gold to manufacturers."

If GreenTech is the innovator, EcoCycle is the reliable workhorse. This Shanghai-based supplier has been around since 2005, and their reputation for durability is legendary. Their flagship WCB-2000C wet separation plant is built like a tank—literally. Plant managers joke that you could ｄｒｏｐ a toolbox on it and it would keep running. But don’t let the tough exterior fool you: inside, it’s all precision.

EcoCycle’s secret weapon? Their water process equipment. Unlike dry systems that can struggle with fine particles, their wet separators use a carefully calibrated mix of water flow and gravity to separate metals from non-metals. It’s like panning for gold, but on an industrial scale—efficient and gentle on the environment. They’ve also nailed the water recycling loop: over 90% of the water used in their wet processes gets cleaned and reused, slashing utility bills.

While they’re best known for wet processes, their dry systems (like the compact granulator with dry separator) are perfect for facilities short on water. It’s this versatility that lands them at number two.

CleanWave is the new kid on the block, but they’ve already shaken up the industry with their lithium battery and circuit board hybrid systems. Founded in 2015 by a team of PhDs from Tsinghua University, they saw a gap: as electric vehicles and smartphones explode in popularity, recycling lithium batteries and circuit boards together is becoming a necessity. Their answer? A 500-2500kg/hour lithium battery breaking and separation system that works seamlessly alongside their circuit board recyclers.

What’s impressive is their filter press equipment. Lithium battery recycling often leaves behind a messy "paste" that’s hard to handle, but CleanWave’s presses squeeze out every ｄｒｏｐ of usable material, turning waste into a valuable byproduct. "We now sell the leftover paste to battery manufacturers for reuse," says James Chen, CEO of a recycling startup in California. "CleanWave didn’t just solve our waste problem—they opened a new revenue stream."

BluePlanet is all about the little guys. Based in Guangzhou, they specialize in compact, affordable systems for small to mid-sized recyclers who don’t have the space or budget for giant machinery. Their star product? The WCD-200C cable and circuit board combo machine. It’s compact enough to fit in a 20ft container but tough enough to process 500kg/hour of mixed e-waste, from old phone chargers to laptop motherboards.

What wins people over is their after-sales service. Unlike some suppliers who disappear once the machine is installed, BluePlanet’s tech support team is available 24/7. "When our WCD-200C jammed during a midnight shift, their engineer walked us through the fix over a video call in 15 minutes," says Raj Patel, who runs a small recycling shop in India. "You don’t get that kind of care from the big brands."

They’re also leaders in wet process innovation for tight spaces. Their water treatment units are modular, so you can add stages as your business grows. For recyclers just starting out, this "grow-as-you-go" model is a lifesaver.

GoldenResource has a knack for turning "impossible" e-waste into gold—literally. Their WCB-005C wet separation plant is famous for extracting gold from circuit boards with such precision that a single ton of e-waste yields up to 300 grams of gold (that’s over $15,000 at current prices!). How do they do it? Their proprietary chemical-free leaching process uses only water and biodegradable surfactants, making it safer than traditional cyanide-based methods.

They’re also pioneers in CRT recycling—those old bulky computer monitors and TVs that most recyclers avoid. Their CRT crushing and separation machines safely remove leaded glass and recover copper coils, turning a liability into a revenue source. It’s this ability to tackle niche recycling challenges that earns them a spot in the top 5.

SmartCycle is for the tech geeks. This Shenzhen-based supplier crams more smart features into their machines than a high-end smartphone. Their circuit board recycling plants come with AI-powered sensors that adjust settings in real-time—if the machine detects more plastic than usual, it automatically slows down the shredder and increases air flow to improve separation. It’s like having a PhD in recycling engineering built into the system.

Their dry process equipment is also a standout. Traditional dry separators often struggle with static electricity, which makes metal and plastic particles stick together. SmartCycle’s anti-static nano-coating solves that problem, boosting purity rates by 5-10% compared to competitors. "We used to have to manually sort through the output to pick out plastic bits," says Tom Wilson, a UK recycler. "Now SmartCycle’s system does it all, and our labor costs have dropped by 40%."

They’re not cheap, but clients say the investment pays off in 18-24 months. For facilities that prioritize cutting-edge tech and long-term efficiency, SmartCycle is worth every penny.

EcoMachines Group is a global player with a local touch. With offices in Dubai, Houston, and Berlin, they understand that recycling needs vary by region. In the Middle East, where water is scarce, they push dry process systems like their 500kg/hour compact granulator. In North America, where regulations are stricter, they emphasize their air pollution control systems and water treatment units.

They’re also big on sustainability themselves. Their factories run on solar power, and they offset 100% of their carbon emissions. For clients who want to market their recycling as "green from start to finish," this is a huge plus.

PowerRecycle is the heavyweight champion. When you need to process mountains of e-waste—think 2000kg/hour or more—their WCB-2000C wet separation plant is the only game in town. Built with industrial-grade steel and triple-reinforced motors, it’s designed to run 24/7 with minimal downtime. "We’ve had ours for five years, and we’ve only replaced the belts twice," says a plant manager in Texas. "It’s the most reliable machine in our facility."

What’s their secret? They source components from top-tier suppliers—German motors, Japanese sensors, Italian hydraulics—to ensure durability. Yes, it costs more upfront, but when you’re processing 16,000kg per day, downtime costs far more than the machine itself.

They also offer turnkey solutions, handling everything from installation to staff training. For large corporations or government-run recycling centers, this "hands-off" approach is a major advantage.

GreenVision is all about second chances—for both e-waste and old factories. They specialize in retrofitting existing recycling lines with their high-efficiency components, so you don’t have to tear down your current setup to upgrade. Their filter press units, for example, can be integrated into almost any wet process system, improving water purity and reducing chemical usage by up to 30%.

Smaller recyclers love their "GreenStart" program, which offers low-interest financing for startups. "I had a great business plan but no capital," says Ahmed Hassan, who started a recycling plant in Egypt with GreenVision’s help. "They gave us a 5-year loan with no payments for the first year. Now we’re expanding to a second location."

While they don’t have the flashiest tech, their focus on accessibility and community support makes them a favorite among underdog recyclers.

Rounding out our list is GlobalEco, a Hong Kong-based supplier with a global footprint. They’re known for their innovative portable equipment, like the PHBM series of metal powder compressors. These compact machines are a hit with remote mining operations and small-scale recyclers who need to process waste on-site. "We use their PHBM-003 in our Congo lithium mine," says a mining engineer. "Instead of shipping scrap metal back to China, we compress it into briquettes on-site and sell it to local foundries—it’s a win-win."

Their circuit board recycling plants are solid too, though not as advanced as the top players. What sets them apart is their network—with warehouses in 12 countries, they can deliver spare parts in 48 hours or less, a lifesaver for facilities in remote areas.

For recyclers who value global support and versatility, GlobalEco is a smart choice.
